' A TTORNE Y Patented Aug. 26, 1952 UNTED STATES PATENT srirroarrne AsgEThis invention relates to evaporative coolers and it has particularreference to supporting fabrication designed to retain the cooleroperatively in relation to a window opening.

The principal object of the invention is to reduce materially the costfor erecting supports for window coolers, especially above the groundfloor and to provide internal structure which makes feasibleinstallations of large evaporative cooler units in double hung windowswithout the necessity for additional external support. As a generalrule, the weight of the unit is such that sub-bracing is needed, bearingagainst the building wall to support the cooler. Such bracing isunattractive and expensive and falls far short of providing adequatesupport. The invention affords a support which is not only strong anddurable but of pleasing appearance.

Another object of the invention is to provide a window enclosureassembly adapted to embrace the duct through which air enters the roomafter penetrating the filter mats of the cooler, said assembly beingadjustable to accommodate the same to windows of various widths. byvirtue of a longitudinally adjustable supporting strap within andadjacent each side of the cooler and which extends from a lower outercorner thereof to the window enclosure assembly, the cooler isstabilized against lateral stresses as well as alleviating undue strainon the duct assembly. Broadly, the weight of the mass is distributeduniformly within the supportingfabrication and much of the Weight isborne by compression bolts carried by the lower support assembly of thecooler and which beara'djustably against the building wall below thewindow.

With the foregoing and other objects in View, the invention has furtherreference to certain features of accomplishment which willbecomemanifest as the description proceeds, taken in connection with theaccompanying drawings wherein:

Figure 1 is a vertical sectional view of a cooler shown mounted in awindow.

Figure 2 is a perspectiveview of the cooler supporting assembly on areduced scale, in which the cooler is shown in dotted lines.

Figure 3 is a longitudinal sectional view taken on line 3-3 of Figure 1.

of the drawing, reference numeral Ill denotes the cooler housing whoseside and rear walls are louvered and removable for readly access tofibrous filter mats. therein, which have been omitted from the drawing.The housing is adapted to contain a blower effective to influence airthrough the filter matswhich are kept saturated by waterelevated by apumpynot shown, from the reservoir inthe bottom of the housing, in theusual'manner. ,The air is cooled by its passage through theflmats and isdischarged through an opening, I I, embracedby a duct assembly [2, whichlatterv conveys the air into a room. Directional control of the air asit emerges fromthe duct .lZlisv accomplished by verticallyand-horizontallyarranged and adjustable louvers l3... r I v The windowenclosure assembly of the invention is comprised primarily of an uppersupport in the form of a plate 14, the'inner end of which is flangedupward at l5, and secured. by screws 16 to the inner face of .the lowerwindow .sash frame I! which is lowered against the plate M in the mannerrevealed in Figure 1. 'Theplate I4 is of the samewidth as the duct l2and its outer end is upwardly flanged at [8 and is apertured to receivebolts .19- which, extend through the front wall of the cooler housing,serving jointly to secure the plate [4 to the housing and to anchor theupper end of the supporting strap assembly, consisting of theaxiallyaligned straps The upper section 20 of thesupporting strap assembly isattached at its upper end to a support angle 22, the latter beingsecured by the bolt [9. The lower section2l of the strap assembly issecured at itslowerfend to a lower support angle 23 which extends alongthe bottom of the housing adjacent the rear wall thereof. Two assembliessuch as. above described are required, one being adjacent each side ofthe housing but thesefassembli'es',lthat is, the straps 20 and 2|, aresufficiently spaced apart to accommodate the-blower and motor, not

shown, which; are support'edon the parallel rails compensate for slightvariations in relationship of companion elements of the support assemblyas a whole or for minor inaccuracies in manufacture.

Mounted for lateral adjustment on the plate I4 is a pair of reinforcingangles 21 (Figs. 2 and 4). These angles are each slotted longitudinallyat 28 to receive spaced apart bolts 29, anchored in the plate 14, sothat the angle memher 21 may be moved inwardly or outwardly, dependingupon the width of the window in which the unit is being installed. Theend of each angle member is turned upwardly at 36 and secured by woodscrews to the window frame, in the manner shown.

The lower supporting assembly is made up of a plate 3| below andparallel with the plate I4 of the upper support assembly and lies underthe air duct l2. The inner end of the plate 31 is broken downwardly,thence forwardly at such an angle that it will lie flush against thesill 32 of the window '(Fig. l), to 'which'it is secured by wood screws33. The plate '3l is bent intermediate its ends to .form a'vertica'l.portion 34 which bearsfiush against .the front of thehousing l .and isturned outwardly atits lower ends, thence upwardly and again outwardly,the end thereof engagingthe bottom of the cooler housing. The plate andthe vertical portion 34 thereof are each provided with side flanges 35,

the inner ends of which are joined by a gusset plate 36, to reinforcethe support assembly.

Theparticular manner inwhich'the lower end of the vertical portion 34of'the .plate 3| is formed, as above described, creates a channel 3'!under the forward end of the housing I!) and is reinforced by a gussetplate 38 at each end. The flanges of this channel have aligned aperturesnear each end through which are passed carriage bolts 39. vA nut 40 isthreaded onto each bolt against which rests a portion of the weight ofthe'housing since the heads 4.! of the bolts bear against the wall 42 ofthe "buildin underneath the window.

The full weight of the'housing 1-0 is distributed between the upper andlower supports, the upper support together .with the supporting strapassembly, being under tension while the bolts 39 are under compression,as imposed throughthe lower support.

After the upper support is installed as described, the housing iselevated into position so that duct vI 2 will be disposed in the windowopening. The side reinforcingangles 21 are set "into position afterfirst centering the duct with respect to the window. .Theiower'supportispositioned so thatthe inner edge of the plate 3| will bear againstthewindow stool and is secured by the screws .33. The window sash frame I;is brought down against :thetop of'the duct l2 and the upturned .flangeof plate 14 is secured to the sash frame by screws 16.

A spirit level isfplacedon the housing It! and adjustment is made in thelength of the strap assembly 2l until the housing is made level. At thesame time,thejnuts on the compression bolts 39 are moved "to insure thatthese bolts assume at least apart of "the load with the housing In in alevel position in order to relieve undue strain on the window sash framel7.

It is obvious that any adjustments interiorly of the coolerhousing-maybe made from within the room, which is a desideratum when thecooler is installed in windows above the ground floor. Afterinstallation and following any required adjustments, the louver assemblyI3 is installed along with side extension panels 42, which are mountedvertically behind the window sill and sash frame (Fig. 2) on each sideof the duct l2 to close the space not occupied by the duct.

Manifestly, the construction as shown and described .is capable of somemodification and such modification as may be construed to fall withinthe scope and meaning of the appended claims is also considered to bewithin the spirit and intent of the invention.
